Definitions

  • the invention relates to an insulation displacement terminal having at least one wire receiving slot provided at each end thereof for the insertion of respective wires therethrough; wherein placing wires in the wire receiving openings and rotating portions of the terminal relative to the wires, terminates the wires in the wire receiving slots of the terminal.
  • terminal blocks are set up in arrays for receipt of wires therein.
  • Many of these terminal blocks are simply threaded members fixed with insulation material which receive wires either wrapped around the threaded members and secured thereto by an application of a nut, or the wires are terminated by known spade or ring terminals and then secured to the threaded member by a nut. While these have, in some instances, provided effective means for termination, they have not always been convenient for maintenance or repair and they frequently are subjected to environmental degradation with a resulting loss of desired electrical characteristics.
  • the telephone wires coming from the phone company can either be in the form of buried cable or aerial wires.
  • the terminal blocks would be mounted in either an enclosure on the aerial mount, or in an enclosed pedestal affixed to the ground, or on a pole. As new telephones are installed in a selected locality, the phone wires are then terminated to the respective terminals on the high density array.
  • wire sizes within the industry are not always the same gauge and therefore the terminals must be designed to accommodate more than one wire size.
  • a typical size wire running from the terminal block to the phone installation is steel wire with a gauge of 181/2 AWG, although, other phone installations use copper wire having a gauge of 22-24 AWG. It can be appreciated then, that a terminal having a higher quality means for terminating conductors and having means to accommodate more than one wire size, would be a substantial improvement within the industry. While the preferred embodiment of connector disclosed herein is for telecommunications applications, for example for electrical interconnection of tip and ring voice signals, the invention could be used with other wire sizes and in other applications.
  • U.S. Pat. No. 4,431,247 shows an insulated terminal and module, however the shell of the terminal only includes one wire opening for insulation displacement.
  • this system is designed for two gauges of wire, where at least one of the wires is 181/2 AWG steel.
  • the previous designs particularly those shown in U.S. Pat. No. 4,705,340; turn the wire into the slot relative to the axial centerline, which causes a bending of the wire.
  • This bend particularly in the steel wire, causes a stored energy spring effect, which over time, can attempt an anti-rotation of the cap tending to loosen the termination.
  • the present invention utilizes insulation displacement technology to enable termination of a number of wire sizes in an environmentally protective manner with the termination being reusable and requiring only a common tool.
  • an electrical connector including an insulation displacement type connector for terminating a conductor of an insulated wire which comprises an insulating housing having at least one terminal receiving cavity defined by a cylindrical wall, and a wire receiving opening through the wall into the interior of the cavity.
  • a cylinder is formed of a conductive material and defines a tubular wall which has at least one wire receiving entry through the wall of the cylinder which is in communication with a slot that partially extends circumferentially around the terminal.
  • a cap is positioned adjacent to the cylinder and is rotatable with respect to the housing and has means for engaging the cylinder for simultaneous rotation of the cylinder with the rotation of the cap.
  • the cap engages the cylinder and rotates the terminal into the wire, and terminates the conductor of the insulated wire within the slot in the terminal.
  • the wire is held stationary, and the terminal is rotated into the wire.
  • another aspect of the inventive connector includes an insulative base member which comprises a floor with a post upstanding from the floor, the post having a through opening for receipt of the insulative wire, at least partially therethrough.
  • a first terminal section is receivable over the post with an interconnection means to a conductive element, with the first said section being stationary relative to the base member.
  • a second terminal section is electrically engagable with the first terminal section and the second terminal section has a wire receiving opening in communication with a conductor terminating slot, the wire receiving opening being aligned with the through opening in the post.
  • the connector further includes means to rotate the second said terminal section relative to the first said terminal section.
  • an electrical terminal comprises a first section of terminal of generally cylindrical shape having a first conductor connecting section, and a second section of terminal of generally cylindrical shape profiled for engagement with the first said section, the second section including a wire receiving opening through a wall of the section in communication with a wire receiving slot, such that when a wire is placed through the wire receiving opening and proximate to the wire receiving slot, rotation of the second section of terminal rotates the second section into the insulated conductor and terminates the conductor of said wire within the slot of the terminal.
  • the top portion of the terminal is removable relative to the lower portion of the terminal In this manner, if the upper portion of the terminal is damaged, the upper portion of the terminal is simply removed and thrown away.
  • the lower portion of the terminal runs a low risk of damage as it is not moveable and it is terminated to a lower wire prior to potting. In other words, the lower terminal, if it is going to be damaged would more than likely get damaged during the termination of the lower wire; and in that event the replacement of the lower portion of the terminal is easily handled, because the lower portion is not yet potted in place.
  • our invention has simplified the installation of the terminals to the wires, thereby providing an easy and cost effective means to install the terminals on the layered cables or aerial wires.
  • each terminal has an insulation displacement section at either end thereof. This allows the installer to terminate all the wires, including the wires of the phone company and the like, by means of rotary installation displacement techniques, thereby eliminating the need for the installer to splice the wires to an intermediate cable.

  • the array is then ready for field pedestal installation, or for mounting within an enclosed aerial mounting box or pole.
  • the individual wires of the multi-conductor cable are then connected to corresponding wires of the phone company, either the buried cable or aerial drop wires.
  • a further discreet wire can be terminated within the connector by inserting a discreet wire such as 370 or 372 through either of the through openings 10 or 12 in the silo.
  • a discreet wire such as 370 or 372
  • the wire will project into the connector into the interior of the post 50 as far as surfaces 58 to prevent the wire from passing through the post into the small wire terminating section.

  • the wire receiving edges 216 through 246 have gaps between them, slightly smaller than the diameter of the conductor to be terminated such that movement of the wire into the slot causes the leading edges 214 through 244 to sever through the insulation of the insulated conductor and place the bared conductor between the edges 216 through 246 in a contacting relation.
  • the post acts as a selector for the particular gauge of wire to be inserted within the terminal and it acts as a bearing surface for the anti-rotation of the wire during the termination of the wire. Further bearing surfaces are provided by the leading edges of the openings 170, 180, 150 and 160 in the lower terminal portion 100, and against the leading edges of the openings 12 and 10, and of the channel 16. It should also be noted from the progression of FIGS. 4A through 4C that the wire remains in a straight condition during the termination thereof.
  • the two piece terminal allows one terminal portion 100 to be fixed, while allowing the second terminal portion 200 to rotate relative to the first portion 100, yet maintain electrical continuity between the two by virtue of the raised projections 190 on the terminal portions 100 being in contact with the slots 206 and 208 in the upper terminal portion 200.
  • the upper 200 and lower 100 terminal portions are kept in electrical engagement by the close proximity of the respective concentric surfaces of the post 50, the inner terminal portion 100, the outer terminal portion 200, the inner and outer surfaces of the cylindrical portion 306 of the cap 300 and the inner surface 14 of the silo 6 or 8; as shown in the FIGS. 4A-4C.
  • the two opposed slots 216, 226; and 236, 246 on opposite sides of the outer 200 terminal could be sized for terminating the same sized wire; thus instead of alternately terminating two wire sizes, the wire always protrudes through to the channel 16 and the wire is terminated within two slots, thereby providing for a redundant interconnection.
  • An electrical connector 500 has a first insulative housing half 502 and a second insulative housing half 504.
  • the first insulative housing half 502 includes a plurality of silo members 506, 508 disposed in two rows.

  • Each silo member has an internal structure essentially identical to the internal structure of silo 8 previously described. Therefore a detailed description of silo members 506, 508, 510, 512 will not be provided.
  • a base or lower terminal section 520 is shown in the formed position. As is shown, the side edges 522 and 524 are positioned so that the edges are provided in substantially abutting relationship. It should be noted that an upper portion 526 (as viewed in FIG. 14) of the lower terminal section 520 have large wire openings 528 which are provided in alignment with respective small wire openings 530, thereby providing the means required to accept the various wire sizes which will be provided in the connector, as was previously discussed.
  • the lower portion 532 of the lower terminal section 520 has only a plurality of small openings 534 provided thereon. The openings 534 provided in the lower portion 532 are utilized to terminate the respective discrete insulated wires of the cable supplied by the phone company. Consequently, as only one size wire is utilized, the openings provided can all be of the same configuration, thereby providing the terminals with a means to provide redundant contact points.
  • the lower terminal sections 520 are inserted into the electrical connector 500 through respective silos. Each terminal is positioned in alignment with a silo and inserted through the end thereof. Insertion is continued until the ends of the terminal are approximately flush with the ends of the respective silos. With the terminals fully inserted into the electrical connector, a potting material is inserted into an inner cavity of the housing halves 502, 504 through an end thereof. The potting material provides the environmental seal required. In the alternative, if the housing halves 502, 504 are sealed together, no potting or encapsulant material is required, as no environmental seal or holding means is required.
  • sections 550, 555 and caps 560 are essentially identical to the operation of upper sections 200 and caps 300. Therefore, a further explanation of these various parts will not be undertaken. However, as shown in FIG. 14, sections 550, 555 and caps 560 are provided at either end of the lower terminal sections 520. This allows the rotary IDC type termination to be used at either end of the terminal. Sections 550 and 555 are essentially identical, with the exception that the only one size slot is provided in section 555.
  • the electrical connector 500 With electrical connector 500 fully assembled, the electrical connector is installed in an opening 580 of a substrate 582, as is best shown in FIG. 12. Mounting of the connector onto the substrate is done by any conventional mounting means. The mounting of the electrical connector 500 on the substrate 582 allows the the silos on either side of the electrical connector to be easily accessed.
  • An advantage which is provided by the embodiment shown in FIGS. 12 through 14 relates to the ease of installation of the electrical connector 500 in field applications.
  • no preparation of the connector is required prior to the connectors use in the field.
  • the wires of the phone company are connected directly to the terminals of the electrical connector, eliminating the need for the intermediate cable. Allowing the phone wires to be terminated directly to the terminals also provides the installer with an easier method of termination. Rather than being required to splice wires together, the installer inserts the wires into the openings, rotates the cap, and the wires are terminated, thereby requiring much less time to terminate the wires.
  • openings 600 are positioned to weaken the strength of the metal used in the manufacture of the terminals.
  • a copper-nickel-tin alloy such as CNS 725
  • CNS 725 copper-nickel-tin alloy
  • This type of alloy is relatively strong and therefore, difficult to bend.
  • the removal of the metal from openings 600 sufficiently weakens the metal so that the metal may be formed in the configuration desired.
  • the removal of the metal also reduces the overall cost of the terminals, as the removed scrap metal can be reused.
  • the positioning and the number of openings provided on various terminals is dependent on the characteristics of the metal used and the final configuration desired for the terminals.
